[QUOTE="Johny25, post: 353935, member: 7791"] Ok hold up! I am sorry but I have to interject some knowledge here. First off the dolphin will not help top speed at all.....sorry. It helps keep boat on plane at lower speed and helps boat plane out, no top end increase. In fact it can do the opposite to top speed if not set up correctly. Second if you want the correct prop to get top speed then post your current prop specs, RPM, GPS speed and make and model of motor. This will let me know your gear ratio and recommended RPM for the motor to give you a better idea of correct prop now that you did mods to engine. DO NOT BUY A PROP BECAUSE SOMEONE TOLD YOU OVER THE PHONE IT WOULD BE OK! TRUST ME.....You have a high risk of wasting your money and messing up your motor. They are designed to run at a specific RPM range and just guessing without proper info can take away life of your motor or ruin it entirely [/QUOTE]
